JOURNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 244,192, dated July 12, 1881.

Application filed March 29, 1881.

T 0 all whom it may concern:

Be it known that I, OHAUNcEY D. CRANDAL, of Hawk Point, in the county of Lincoln and State of Missouri, have invented certain new and useful Improvements in Journal-Boxes; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing, and to the letters of reference marked thereon, which forms part of this specification.

This invention has for its objects to provide an improved journal-box which will be simple and efiective in use; which will be much more durable than the ordinary boxes, and consequently cheaper in the long run, and in which the bearing-surfaces maybe renewed at a trifling cost, when worn, without necessitating a new box; which will keep the shaft truly in line no matter how often the wear is taken; which can be tightened whenever required, and thus prevent all play of thejournal,as more fully hereinafter specified. These objects I attain by the devices illustrated in the accompanyin g drawing, in which the figure represents a central vertical section of ajournalbox such as I describe.

The letter A indicates the journal-box,which is formed with circular transverse seat B, having a transverse slot or opening, 0, at the bottom, in order that the shoulders upon the fillin g-rin g may project through against the band or strap, and thus be tightened by compression as the ring wears away. Within the seat is located a transversely-split ring of brass, or anti-friction metal or alloy of any suitable description. The ends of the ring are provided with shoulders D, which rest against the edges of the opening 0, and the said ends are beveled or rounded on top, against which rounded surfaces the metallic strap D is adapted to bear. Both the strap and the ring are provided with an aperture, E, for the introduc- (No model.)

tion of oil or lubricant to the journal. The strap is secured to the box at each side by means of screw-bolts or screws F, in such manner that it can be tightened from time to time in order to compress the ring and compensate for wear.

It will be observed that as the ring always maintains its original position in its seat irrespective of the amount of compression, the shaft will always be kept truly in line, while at the same time all wear can be readily taken up, so as to prevent any play ofthejournal, and that when the ring is so worn as to become useless a new one maybe substituted at little expense and employed with the original box, as the seat therein never becomes worn, rendering the box comparatively indestructible.

Having thus described my invention, What I claim, and desire to secure by Letters Patcut, is-

1. A journal-box provided with a transverse circular seat open at the bottom, in which seat is adapted to be fitted a transversely-split ring having shoulders at its ends, and beveled or rounded, as described, and a metallic strap, adapted to be secured to the box and tightened against the ends of the ring by means of bolts or screws to compress the ring and compensate for wear, substantially as specified.

2. The combination, with the box having a transverse seat open at the bottom, of the transversely-split ring, the confining-strap, and fastening devices, constructed and arranged substantially as herein described.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
